Subject: Lot 15, Block 8, The Tablelands Subdivision
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer.
The groundwater level on Lot 15, Block 8, The Tablelands Subdivision has
unexpectedly risen making our original design for the septic system for this property no
longer usable. We are therefore proposing to place an Advantex Septic Treatment
System for a five -bedroom home on the property. The attached Site Plan and backup
documentation identify the location and configuration of the new septic system and
alternate site and the parameters used in the design. Also identified on the plans are
the location of the surface drainage, test holes and water service on the lot. The
system will not conflict with those on the surrounding lots. Drainage arrows and spot
elevations are shown indicating the current drainage patterns. The drainage patterns
will be maintained after construction.
The test holes placed on this lot revealed silt with some sand. The percolation rate in
the upper layers ranged from 40 minutes to 60 minutes per inch. Groundwater was
recently noted at 3' below the surface. We are therefore proposing to place a five -
bedroom Advantex Treatment System. The terrain of.the lot is such that gravity flow
from the filter to the absorption bed is not possible and a second lift station will be
required. The absorption bed will be 50' long x 15' wide for a total absorption area of
750 square feet. The bed will be constructed at the existing ground level. Approximately
1' of clean coarse sand will be required to replace the organic layer removed below the
bed and to level the bed area.
The ground surface on the lot slopes as shown on the site plan from west to east at
shallow slopes. The absorption bed will be constructed parallel with the slope as much
as possible in conformance with Municipal requirements. All components of the new
Lot 15, Block 8, The Tablelands
May 26, 2005
Page Two
septic system will be constructed a minimum of 100' from any surface water and 10'
from the water service on this and adjacent lots.
If the system is constructed in accordance with our design the following statements
apply:
1. The system, if constructed as designed, will have no adverse impact on the wells
in the area or those to be constructed in the future.
2. The system, if constructed as designed, will have no adverse impact on existing
septic systems in the area or those to be constructed in the future.
3. The system, if constructed as designed, will have no adverse impact on reserve
space, either surface or subsurface, on any lots located in the area.
4. The system, if constructed as designed, will have no adverse impact on drainage
patterns in the area. The current drainage pattern will be maintained.
Sincerely,
Michael E. Anderson, P.E.

Subject: Lot 15, Block 8, The Tablelands Subdivision
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 15, Block 8, The Tablelands Subdivision intends to construct a new
five -bedroom home on the lot. We are therefore requesting a permit be issued for the
construction of a new septic system to serve the new home. The subdivision is
currently served by a community water system. No conflicts exist with adjacent septic
systems or wells and the proposed septic system on this lot. The attached Site Plan
and backup documentation identify the location and configuration of the proposed
septic system and alternate site. The current drainage pattern is identified on the Site
Plan. The drainage pattern will be maintained after development of this lot is complete.
Test holes recently placed on the lot indicated silty gravel with minor amounts of sand in
the area of the absorption trench and alternate site. The accepting soils were tested
and found to have a percolation rate of between 40 minutes per inch and 60 minutes
per inch. The system is designed with an application rate of .3 GPD/SF. Groundwater
was found in the test holes during placement at 10' below the surface and was
monitored during the ensuing period at 7.5' below the surface. Our design includes the
placement of a new 1,500 -gallon septic tank along with 2 - 84' long and by 15' wide
absorption beds to collect and treat the sewage generated in the house. The bottom of
the beds will be 2.5' below the surface. The distribution pipe will be 2' below the
surface. A flow splitter valve will be installed to insure even flow to each bed. A
minimum of 3' of cover will be placed atop the beds and a minimum of 4' of cover will be
placed atop the new septic tank.
The ground surface on the lot slopes at varying grades from north to south as shown on
the Site Plan with steep slopes near the south end of the lot. The absorption beds will
Lot 15, Block 8, The Tablelands Subdivision
April 23, 2005
Page Two
be constructed parallel with the slope of the ground surface as much as possible in
conformance with Municipal requirements. The new septic system will be constructed a
minimum of 10' from the water service proposed for the lot and on adjacent lots. It will
also be constructed a minimum of 100' from any surface water in the area.
If the system is constructed in accordance with our design the following statements
apply:
The system, if constructed as designed, will have no adverse impact on the wells
in the area or those to be constructed in the future.
2. The system, if constructed as designed, will have no adverse impact on existing
septic systems in the area or those to be constructed in the future.
3. The system, if constructed as designed, will have no adverse impact on reserve
space, either surface or subsurface, on any lots located in the area.
4. The system, if constructed as designed, will have no adverse impact on drainage
patterns in the area. The current drainage pattern will be maintained.
Sincer�ely,
j
